AI-powered flight briefing
9,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 9,500 data points along your route from John F Kennedy International Airport, New York to Shannon Airport, Shannon.

Your Journey Beta

3 hours 40 minutes and 5 hours 20 minutes into the flight: Some moderate bumps expected.
The crew may adjust altitude or ask you to stay seated during these sections.
The rest of the flight should be smooth.

Your route takes you over the Appalachian Mountains and crossing the North Atlantic Ocean – these areas can sometimes cause light turbulence.

Smooth Flight

We're expecting smooth conditions throughout your flight. You can sit back and relax.

Takeoff

Takeoff should feel smooth, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 87 knots. These winds are favorable and may get you there up to 56 minutes early.

Landing
